UNITED STATES LILLIAN K. ENGLE, OF LANSDOWNE, BENNSYLVANIA FASTENING- .AND- SUQBOBI EING DEVICE.

Application tiled Qctober- 11-. .1927, serialno. 225,583.

My invention relates to. a new and. useful taste-h ng and suppor ng".dev Qe an mo pa icul rly to de i o hi h efi e hich an e firmly anddeteqhe ly ec e to fasten and support diflferent objects to eachother'lor to a suppor t withoutithe'ei'd of an y external or auxiliaryeans.-

My invention further relates to a fasteningand supporting device whichmaybe employed in the vertical horizontal or pendant positiomthatis,'one which is adaptedto resi st lateral, downward'and upward. strainor ull. i I p My invention further relates to. a novel device of thischaracter wher ein the'piercing o a e ng. ele nt are int with thsupporting or retaining element, the entire device being madeof suitablesheetmetal or the like, by a singlestamping, punching or castingoperation.

'110 the above ends, my, invention consists of a double .hook, piercingarms or, prongs on either side of said hook, a base common to said hookand said prongs and forming a right angle therewithflnd a pair ofdoubledpiercing arms integral with and extending from eitherencl'of'the'opposite edgeof said base in parallelism. therewith, said"prongs and doubled arms beingprovided with novel means for interlockingwith the fabric or other material, said elements being also providedwith bottom grooves forming stiffeningribs.

M'y'invention further consists in so'constructingthe Hiercing arms andi'prongs above referred 'to, aslto afford a firm, detachable engagementwith the object beingjfastened or supported, and to-reduceithe holesorperforations made bysaid prongs arms'to a minimum.

My invention further consists in providing the prongs and base abovereferred'toiwi-th" reinforcing ribs to adapt my novel device 'for heavy.duty without materially increasing the weightor dimensions th reof: 7

My invention further consists in various other features of' constructionandfcollofca- .tion of parts as hereinafter described. 7

For the purpose of il lustrating my invention, I' have shown in the,accompanying drawings, forms thereof which are "a'tfp'res ent. pre

e ed as e thgy v ls re i111 practice, satisfactory and reliable results,although it is to beunderstood that the various instrumentalitiesofwhich my invention con sists canbc variously arranged and organized andthat my invention is not limited to the 'precise arrangement andorganization. of

device shown detached.

Fig, 6 representsa plan view of a modified construction embodyingmyinvention. Fig. 7 represents an end view of a further modified formembodying my invention.

Referring to the drawings, in. which like reference characters indicatelike parts, 1 designates a fastening andflsupporting .device embodyingmy invention comprising the relatively long, slightlyco-nverging,.pointed, tapering prongs 2, the relatively, short, pointed,oppositely disposed, doubled arms3, and; the intermediate, lntegral baseor connecting body portion 4., From the base Land integralthere'with,jextends the arm or tongue '5 having the humped; portion 6',said aim being bent back upon itself to form the hook and lie/mgcontinued rearwardlyto, form. the arm'8 whichis similarly humpedas at 9,the humps 6and-9'on the arms 5and' 8 respectiueiy forming a lock orclosure for the 'doubledhook. or re ta'ining. member 7', as will ej nd seed f om F gs 3; 4' and The tapering, piercing prongs 2 -a-nd 3 areprovided with the recessed portions-l0 which serve to interlock with theWeave or warp and weft of'a, textile fabric such as a curwin or othermaterial into which they. may be inserted. Another advantage of the,re.- c'essed portions 101is that'wlienthe material is initiallypierced'by the prongs 2;.and arms 3', a hole or opening is made, "liarie enough to permit of: thepassage ofthe'widest portio 11 of said prongsand arms, and if the material is permanently thus distended, when theprongs and arms are withdrawn, a relatively large hole or openingremains, since the warp and weft of the material having been widelyparted over a long period of time, fail to resume their normalpositions, due to the loss of elasticity. By providingthierece'ssed portions 10, however, the fabric, and particularly the warp and weft of thefabricfnot having lost their inherent elasticity, will tend to resumetheir normal positions around the, recessed portions 10 and-being thusnot widely parted or distended, only a small hole will remain after-theprongs and arms are Withdrawn from the fabric.

Thebase 4, the prongs 2Iandthe armsB,

with respect to the curtain 1 3 is-possible,

since any tensi'on,'such as the weight of the curtain 13, exertedv onthe. device, merely serves further-to strengthen theengagement of the;prongs and arms 2 and 3 with; the body of the fcurtain, the book -7being in turn prevented from being detached or object, either by itsposition as inllig. 1, or by the contaotir g locking humps or knobs 6and 9.

In F 6 I have shown a modified form ',of my invention wherein theprongs, 2 are relatively thin throughout their entire length and areprovided with the swelled or enlarged portions 15 which fservle tointerlock with the elastic, contracting warp and weft of the fabric toprevent slipping. In this construction also, only a small, practicallyinvisible hole remains afterthe prong iswithdrawn, since the cloth orfabric 'is I only temporarilydistended ,or parted wide enough to permitof the passage pf the'en-, 'larged portion 15, after which the warp andweft. adjust" themselvesaround the relatively thin; portions 1 6 ofth'e-prongs2,

InQFig. 7 I have shown a further modi fied construction, wherein theprongs ,2, ,of the modified-construction shown in Fi 1and-6,are.corrugated orwaved asat 'l to afford a .firiner. engagementvof the prongs with the fabric if. so desired.

It will thus "be seen thatQIhave devised a novel fastening andsupporting device which iscompact, neat andserviceable, and

curtain rod not working loose from the ring '14 ordother ,comprising adoubledho ok, parallehpiercone which can be manufactured. economicallyby a single stamping or punching operation. It will also be seen that mynovelfastener can be secured to a fabric or similari; inaterial withoutthe use of stitches.

of which are at present preferred by me since they will give-1n practicesatisfactory and reliable results, it isto be understood that such formscan be varied without departing from, the scopeofmy invention orsacrificingany, of itsadvantages.

Having thus described my invention, what I claim as newand, desire tosecure by LettersjPatent is; l I
